Hello,

I am running a dell power edge 2950 with windows 2000 sp4 and exchange 2000 standard sp3.  I have had this issue for about a month now and it is starting to really bug me.  I am getting warning and error codes 9582 about every other day and once it starts, it doesn't stop until I restart the msexchangestore.exe service.  I did every thing listed under this MS article:

http://support.microsoft.com/default.aspx?scid=kb;en-us;325044 

and I am still having this issue.  I think I have a VM leak because the store is losing about 50mb of space every hour from what the log files say.  If I restart the store.exe, it goes back to 1.5gb and so the cycle continues.  I am not running any kind of Anti-virus software on the box and I have about 35 users through out the day.

Please help!

GFI Mail Essentials?
I have seen that product cause something similar before. Make sure that you have the latest build. When it happened before removing GFI, then rebooting the server and reinstalling it (ensuring that the latest build was used) fixed the problem.

Have you run the Exchange Best Practises tool on the machine to see if that flags anything?

I actually just upgraded to the latest build a couple weeks ago, so I know that is up to date, but why would mail essentials cause VM defragmentation?

I am always suspicious of any third party tools being the cause of problems on Exchange servers. A server with just Windows and Exchange and no third party tools at all rarely causes any problems at all. However as soon as third party tools are introduced you can get problems.

store.exe is part of Exchange, but third party tools also hook in to the store. Therefore as you have identified store.exe as being the source of the memory increase I start looking at third party tools that hook in to the store - GFI is the first one that you have mentioned.

Is there any way to find out what application or process is using VM?

I think you already have - store.exe. That doesn't mean it is Exchange that is causing the problem because third party tools can cause store.exe to use the memory.
You don't really have much choice other than to remove third party tools that are hooking in to store.exe. If you were using an Exchange version that was still under support and called Microsoft, they would tell you the same thing.

Did you remove and reinstall immediately? Was there any period when the application wasn't installed?
Have you confirmed that no AV products or anything like that is scanning directories that it shouldn't? Defrag or other disk utilities likewise?

I removed gfi and let the server run about 3 hours without it.  Reinstalled and checked all settings.  There is no AV running.  I did shut off the store.exe scanning feature from gfi, but that had no effect

During the time window that GFI was off the server, did you see any virtual memory issues with the server?

I remarked on something else earlier in the question - have you run the Exchange best practises tool on the server to see if that flags anything?

Was that the only thing that was flagged?
I am of course presuming that the server is fully patched with the latest rollup etc on the server?

Yeah, it's all patched.  Nothing else was flagged that is worth noting except that the temp path is located on the same drive as the system partition.  I doubt that would cause this problem though.

Hey simon,
   I looked at the exchange build number and after doing the august exchange rollup, it should have changed my build number to the latest 6063 build or whatever it is, but for some reason, it's stuck on my old build number  6249?  So i'm not sure if the updates have been applied to the server.

Do I need another license to upgrade to the rollup?

No - all updates for the same version are covered under your original purchase. you would only need a new license to go to Exchange 2003 or 2007.

Did you check the version of store.exe? That is what usually changes.

Look at the properties of store.exe. The version information is on one of the tabs.
